Improvement in locks for breech-loadimg fire-arms



JOSEPH C. DANE, OF LA GROSSE, VVISOONSIN.

Specification forming part of Letters Patent No. Ei, dated January 20,1874; application led January 10, 1873.

To Il whom it muy concern:

13e it known that I, JOSEPH G. DANE, of the city and county ot' LaCrosse and State of Wisconsin, have invented a new and Improvedlrcech-Loading Fire-Arm; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawing forming a part ot' this specitieation, inWhichlfgure 1 is a partly sectional side elevation of a breech-loaderprovided with my improved tiring-pin or strikerl7 t Fig. 2 shows alongitudinal section of the strikerdetached from the lire-arm.

The object ot' my invention is to provide a tiring-piu er striker fordrop breech-loaders which shall occupy less space in the recoilshiehlthan those heretofore employed in guns el' the needle pattern, and yethave the necessary weight to act eiciently on the cartridge by momentum.This I accomplish by providin the striker with an annular flangeprojectiu downward around the pin and over or inclosing the spiralrecoil-spring. Thus ample space is provided for the latter, so that itmay he ot' a length necessary to its due elasticity, while the liangeacts also as a stop to arrest the movement of the striker toward theeartridge at the proper moment, the proportions and arrangement of thedevice being such that the pin is always within the recoil-shield, eX-cept at the instant ot' impact on the cartridge, securing thus theadvantage incident to the ordinary combination of tiring-pin andrecoilhammcr, as hereinafter described. I

A center-tire cartridge-shell, G E, is shown inserted in the breech ofthe dropbarreh The recoil-shield f is provided with an oblique recess toreceive the striker a, and the same is confined therein bythe nipple B,which screws into its place, as shown. The striker is made in one piece,and with a shoulder near its upper end, which7 when the hammer d israised, is in contact with the inner end of the nipple, and has anannular recess, c, formed in its base or lower end around the pin e, forthe purpose of receiving the spiral spring O. Thecorrespondingly-annular flange/i serves as a stop for the striker whenacted on by the hammer, and also gives it the weight necessary to im-lpart to it the momentum requisite to a proper ettect upon the cartridge.Without the liange the striker would require to be made longer orthicker, or both, thus taking up an undue amount of space in therecoil-shield, or else the spring O would require to be made shorter andthe annular cavity jlled up, thus unduly lessenin g the elasticity'ofthe spring and destroying its proper action.

Ihat I claim is- The striker a, provided with a shouldered head andhaving an annular tlan ge, c', and corresponding recess c for therecoil-spring, said flange extending toward the point of the tiring-pinc to act as a stop, all as shown and described. I
